As he drives slowly across snow，Nils Mathis Sara drops food on the ground for hundreds of his reindeer(驯鹿)to eat. His animals live in Finnmark，the northernmost point of Norway. But Sara wishes he did not have to feed them. This year the snow is too thick and hard，making it impossible for the reindeer to reach their food. "This is an emergency situation," said Sara. "I am not supposed to feed them. They are supposed to feed me."

Sara is part of the Sami community，which comes from the northern areas of Norway. Normally，the reindeer find their own food. They dig through the snow to reach small plants，called lichen(地衣)，hidden below.
But every winter for the past ten years，Sara has had to buy food to help the animals live through the cold season. Winter temperatures in the area can drop to -40℃. At first，only snow fell during winter months，but recently，warmer temperatures have brought rain instead. Then，when the temperature drops，that water turns to ice. The thick ice makes it difficult for the reindeer to reach the lichen. "It is especially hard for the younger reindeer，as their feet are not strong enough to break through," Sara said.
One morning in March，Sara and a relative provided about 1,500 kilograms of food for the reindeer. They've been doing the same thing every other day since February. Though reindeer are partly wild animals，repeated feeding changes their natural behaviour. Normally，herders(牧人)follow the animals as they look for food under the snow. But feeding the animals makes them slowly become less wild and depend more on humans. This makes the Sami people live more like farmers than herders. Sara says this goes against the Sami's traditional way of living. "When we feed the reindeer，they change their behaviour and become more used to humans," Sara said.
